Most of what you perceive as "taste" is just using your sense of smell on food within the mouth, where it is very close to smell receptors.
To isolate taste informally, pinch your nose, stick your tongue out, and put food directly on the tongue when it's outside your mouth. You'll find that by itself your tongue can't distinguish many flavors, that's why everything tastes terrible when you have Covid or a bad cold.
No, the paper says it shares a receptor with sour, not that it tastes like sour.
Just as "orange" and "purple" have receptors in common but are not perceived as the same.
Umami is the fifth flavor. This paper is about the sixth, which doesn't seem to have a name other than "ammonium chloride".
¡At least two of those languages have the same problem!
Or, as millions of people have done, you could learn to read from right to left.
¿And don't you hate how US punctuation is at the end? ¿If you read an entire sentence, but you don't even know it is a question until you're at the end, then how do you know which intonation to use? ¡English is subpar and something should be done about that!
It must be tiring at work waiting for the clock to finally strike 00:5pm.
They are fine with their jobs because they have other jobs that pay them.
Your idea would mean the end of professional musicians. Music performance would be mainly for people with lots of leisure time, something rich people would do as a hobby. Like playing polo.
If your job stopped paying you, and told you to rely on donations from your clients/customers, then I'm pretty sure you'd find a different job.
In a work for hire contract, the contract explicitly states that the employer gets the copyright.
You can think of the compensation as being partly from employment, and partly from the sale of any copyright.
It's not actually called "theft" or "stealing", it's called "infringement" or "violation". Infringement is to intellectual property as trespassing is to real estate. The owners are still able to use their property, but their rights to it have nevertheless been violated.
Also, corporations cannot create intellectual property. They can only offer to buy it from the natural persons who created it. Without IP protection, creators would lose the only protections they have against corporations and other entrenched interests.
Imagine seeing all your family photos plastered on a McDonald's billboard, or in political ad for a candidate you despise. Imagine being told, "Sorry, you can't stop them from using your photos however they want". That's a world without IP protection.
I can't believe it's not battery!
